Most Solatube® Daylighting System extension tube sections have a special notching system that allows one end of the tube to be larger than the other so they can telescope into each other for easy installation. As a result, trimming is rarely necessary.
The exception to this rule is the Solatube SkyVault® Series, a product that was designed for commercial high bay, open ceiling applications that don’t require connecting to a ceiling.
It features an innovative Tab-Lock Connection System with Tube Belts as well as extension tubes that come in pre-determined lengths, which makes cutting the tubing unnecessary.
